BV, this may not be the exact data you are looking for but I remember me and Graph talking about it last year:
http://www.irvinehousingblog.com/forums/viewthread/2519/
Grabbed from the 07 Chapman Forecast ” Ratio of home prices to median family income increased from 4.0 to as high as 9.4 in OC by late 2005. ” I remember it getting down to like 5 or 6 something in 07
I lended IR’s book to a friend so I don’t have the data, but I believe it was 10.6 in 2006 or something.
Do we have the latest median income for OC? we know the latest median house is 397,000
